Last week we had some hands on time with the latest AMD GHZ HD7970. At the end of the day it left us feeling distinctly uninspired. There was no doubt the card was fast, but AMD sadly adopted their ill equipped, painfully loud cooling solution with tiny, single red fan.

We hoped that Sapphire would rectify the sorry state of affairs and today we have their latest HD7970 ‘Toxic Edition’ in our labs, featuring a proprietary dual fan cooler, a staggering 6GB of GDDR5 and a ground breaking ‘lethal boost’ overclock core speed of 1,200mhz.
